2 Claims.

My invention relates to locomotive stokers of the class comprising aplurality of fuel con- Veyors arranged with two of the conveyors olfsetlaterally from each other at their adjacent ends and having independentdrive connections at their rearward ends.

It is the principal object of the invention to improve upon stokers ofthe aforesaid class by substantially reducing the angular relationbetween the conveyors. More specifically, I contemplate the provision ofa stoker having a fuel receiving conveyor on the tender, a fuel deliveryconveyor on the locomotive, and an intermediate conveyor, the latterbeing offset laterally at one end from an adjacent end of one of theother conveyors and said adjacent end of that conveyor disposed at oneside of the vertical medial plane of the locomotive and tender orat oneside of theV vertical medial plane of the other of said .30 conveyors.

Another object is the provision of a specific embodiment of theinvention as above wherein the rearward end of the intermediate conveyoris oiset laterally from the forward end of the tender conveyor.

Y A further object of the invention is the provision of stokers of theclass described wherein the tender conveyor is disposed with the axisthereof lying at` one side of and substantially 3.o, parallel to thevertical medial plane of the tender or wherein said axis extendsdiagonally of and passes through said plane.

Av still further object of this invention is the provision of a stokerof the character specified -Si which is suitable for use inV connectionwith locomotive and tenders of conventional design.

Other objects and advantages of the invention will be apparent as thefollowing description is read in connection with the accompanying draw-40 ings, in which,

In Figures 1 to 5, inclusive, illustrating an embodiment of myinvention, A represents the locomotive, B its tender, and C the couplingmember therebetween, permitting articulation when the locomotive andtender are rounding curves or passing over switches and turntables. Thelocomotive A comprises a boiler l0 having a backwall II in which thereis the usual firing opening I2, establishing communication between thecab I3 and the firebox I4. Above the floor I5 of the tender B is a fuelbin I6, the floor I5 being apertured centrally of the fuel bin as at Il,the' size of which aperture is controlled by the slidable plates I8.

Extending from beneath the apertured oor of the tender to the rebox ofthe locomotive is I a stoker, indicated generally at S. The Stoker Scomprises the fuel receiving or tender conveyor D, the delivery conveyorE, and the intermediate conveyor F. The delivery conveyor E includes aninclined conduit I9 mounted on the locomotive and communicating with therebox I4 through the opening I2, and an elevating or fuel deliveryconveyor screw 2|] housed within the conduit I9 for delivering fuel to adistributing means 2l which spreads the fuel to all parts of the rebedThe elevating screw and the conduit I9 are mounted so that theirrespective axes are in substantially the vertical medial plane of thelocomotive and tender, or so that the fuel deliverymouthof the conduitI9 is disposed substantially equally on each Side of such plane.

The tender conveyor D is rigidly mounted beneath the apertured floorI5-ofl the tender in the compartment 22 and includes a trough-likeconduit 23 provided with an open mouth 24 through which fuel falls fromthe bin I6 into the trough 23. The open mouth of the trough 23 is atleast equal to the widthvand length of the aperture in the floor I5'toprevent loss of fuel. Fuel which is received within the trough-likeconduit 23 is conveyed forwardly by conveyor screw 25 disposed withinthe trough with its axis at one side of and parallel to the verticalmedial plane of the locomotive and tender. The screw 25 extends thelength ofthe open mouth trough 23 and into a tubular extension 26, rigidwith the trough and coaxial with the conveyor screw 25. A sphericalmember 2-1 is formed externally of the tubular extension and at theforward end thereof.

The fuel receiving conveyor screw 25 delivers fuel tothe screw 28 of theintermediate conveyor F'which screw has the forward end 29 thereof lMarch, 16, 1937. C. J. SURDY LoCoivIoTIvE sToKER Nw Mm .y INVENTOR.Wwf/e4 lm/'Jy BY NN www,
